A group of young pirates come from space to Earth to obtain the "Greatest Treasure in the Universe", which can only be acquired after obtaining the Ultimate Powers of the different 34 Super Sentai Teams. However, they end up running afoul of the Space Empire Zangyack, whose earlier invasion forces were wiped out by the 34 Sentai groups long ago. As a result, the space pirates use "pirate copies" of the powers of the older teams and fight the Zangyack forces as the Gokaigers.

Beast-Fist is a form of martial arts where the powers of a beast can be acquired by sensing the beast in their hearts. There are two relative schools of the Beast-Fist. One, the Beast-Fist of justice, Geki Juken Beast Arts. And one, the evil Beast-Fist of Rin Juken Akugata. The two schools of warriors learn and change in order to increase in power every day, as they are destined to clash.
